The Influential Role of the Secretary of State\u27s Office in the Pacific Northwest
The purpose of this research is to provide a cross-state comparison of the role that the Secretaries of State play in their given state as well as the influence it has on national politics. In order to evaluate the role of the Secretary of State, this research will examine states in the Northwest region of the U.S. (i.e. Pacific Northwest) to determine how their formal and informal powers affect their role in their respective state. The driving research question is: what role does this position play in impacting state and national electoral politics in the U.S? In an attempt to address this question, semi-structured interviews will be conducted with staff at the five offices in the Pacific Northwest. Moreover, public administration theory will be applied as a descriptive framework to examine the interview responses. The Secretary of State’s office is an agency that 47 out of the 50 states in United States have in their government – this office can play an essential role in defining U.S. elections and politics more broadly. Moreover, 12 out of the 47 states that have a Secretary of State either appoint via governor or state legislature, while the remainder of the states elects their Secretary of State via the general public. The duties and level of participation of the Secretary of State’s office varies based on the state’s government and the powers that have been allotted to them by their respective state constitution. This research will provide a first hand account of the work that is being done in each office and the broader societal implications
Evidence for a Mid-Atomic-Number Atmosphere in the Neutron Star 1E1207.4-5209
Recently Sanwal et al. (2002) reported the first clear detection of
absorption features in an isolated neutron star, 1E1207.4-5209. Remarkably
their spectral modeling demonstrates that the atmosphere cannot be Hydrogen.
They speculated that the neutron star atmosphere is indicative of ionized
Helium in an ultra-strong (~1.5x10^{14} G) magnetic field. We have applied our
recently developed atomic model (Mori & Hailey 2002) for strongly-magnetized
neutron star atmospheres to this problem. We find that this model, along with
some simp le atomic physics arguments, severely constrains the possible
composition of the atmosphere. In particular we find that the absorption
features are naturally associated with He-like Oxygen or Neon in a magnetic
field of ~10^{12} G, comparable to the magnetic field derived from the spin
parameters of the neutron star. This interpretation is consistent with the
relative line strengths and widths and is robust. Our model predicts possible
substructure in the spectral features, which has now been reported by
XMM-Newton (Mereghetti et al. 2002). However we show the Mereghetti et al.
claim that the atmosphere is Iron or some comparable high-Z element at ~
10^{12} G is easily ruled out by the Chandra and XMM-Newton data.Comment: 5 pages, AASTeX, Revised version. Accepted for publication in ApJ
